Goodmorning all,
I have been playing around for a while now with Openshift Origin on our
LinuxONE system following the great “Getting_Started_with_OpenShift_v3.10”
guide….
When using zVM as a hypervisor I can deploy an Openshift cluster with multiple
nodes with no problems at all (using zVM 6.4 and Clefos 7.5). Everything works
like a charm….
But when I try to deploy an Openshift cluster with one or multiple nodes using
KVM (using Ubuntu 16.04 KVM and Clefos 7.5) I run into problems starting the
docker daemon.
Somehow the docker daemon freezes after which I have to cancel the ansible
playbook…… Starting the docker daemon by hand (systemctl start docker), the
same thing happens:
● docker.service - Docker Application Container Engine
Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor
preset: disabled)
Active: activating (start) since di 2019-09-24 11:00:01 CEST; 8min ago
Docs: http://docs.docker.com
Main PID: 27563 (dockerd-current)
CGroup: /system.slice/docker.service
└─27563 /usr/bin/dockerd-current --add-runtime
docker-runc=/usr/libexec/docker/docker-runc-current
--default-runtime=docker-runc --exec-...
sep 24 11:00:01 lnxicu20 systemd[1]: Starting Docker Application Container
Engine...
The service will remain in status “activating (start)” until I kill the
service. No messages (other than “starting Docker Application Container
Engine”) the logs. Every docker command that you try to give (e.g. docker
version
Anyone seen this behaviour before or any ideas on what is going wrong?
I have a couple of other linux guests (both Ubuntu and SLES) running Docker in
both zVM and KVM environment without any problems….
Some additional information: yum list installed | grep docker
cockpit-docker.s390x 176-4.el7.centos @extras
docker.s390x 2:1.13.1-96.gitb2f74b2.el7.centos

python-docker-pycreds.noarch 1:0.3.0-9.el7_6 @extras
Same situation on linux guests running in zVM and KVM, but only on zVM the
docker service will start.
On the zVM guest the “docker version” command returns:
Client:
Version: 1.13.1
API version: 1.26
Package version: docker-1.13.1-96.gitb2f74b2.el7.centos.s390x
Go version: go1.10.3

Experimental: false
Running the same “docker version” on the guest in the KVM environment results
in a freeze …..
On an Ubuntu guest running in KVM an “apt list —installed | grep docker”
returns:
docker/xenial,now 1.5-1 s390x [installed]
docker.io/xenial-updates,xenial-security,now 18.09.7-0ubuntu1~16.04.5 s390x
[installed]
and the “docker version” command shows:
Client:
Version: 18.09.7
API version: 1.39
Go version: go1.10.4

The Ubuntu environment on KVM has been running perfectly OK for quite some time
now …..
Sorry for the long post, but this is driving me nuts…..
